Cannot invert a matrix with IMSL routine LINDS

I am trying to use a standard IMSL routine LINDS to invert a positive definite matrix,. 

I installed the IMSL library based on these instructions. 

https://software.intel.com/en-us/articles/installing-and-using-the-imsl-...

Then I included the lines 

INCLUDE 'link_fnl_shared.h'

use linds_int

in my program, before setting up the matrix to be inverted

The program compiles without error, but when I debug it it, it exits without inverting the matrix. It  does not trigger a break  point, but it just stops. 

Any help will be greatly appreciated. Thank you very much
